Of the two girls who stayed in the apartment, one decided to sleep over at a friend’s house. This left the other alone in the apartment. As night fell, she suddenly realized she had left her pajamas at home and decided to go back to retrieve them.

Upon returning to the apartment, she decided not to turn on the light to avoid disturbing her roommate’s sleep. So, feeling her way carefully in the dark, she searched for her pajamas in the dim light and, after finding them, left quietly without making a sound.

But here’s the chilling part: the next day, when she returned, she encountered a scene straight out of a horror movie. The police were there! Upon entering, her eyes fell on her roommate’s body lying on the floor, covered with a sheet. But what truly froze her blood was what she saw in the room’s mirror: a phrase written in red lipstick that read, “LUCKY YOU DIDN’T TURN ON THE LIGHT.”
